WINDOW SHIELD.

Application led .Tune 9, 1926 Serial No.7114,695.

My invention relates to new and useful 'improvements in a window shield, particularly adapted for use in connection with vehicles, such as automobiles, street and railway cars and locomotive cabs, and hasjfor its primary object to provide means for blowing a continuous stream of air of large volume in front of the vehicle window, wind shield or the like, so as to prevent it from being covered with snow or rain.

Another object of the invention is to provide means for supplying a large volume of air economically and continuously, if necessary, rather than spasmodically, whereby a window or its equivalent may be kept clear in stormy weather.

blower.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that thoseV skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which:

Fig. 10, is a fragmentary ront elevation of a railway car, illustrating an application of my invention.

Fig,- 11, is a. sectional view thereof.

while above this is the usual cowl 22, and a supplementary inner cowl 23 spaced from the main one, and said supplementary cowl may have a passageway 24 therein, which is controlled by a closure 25 hinged or otherwise mounted under said supplementary cowl.

Projecting from the main cowl 22 is a main wind shield 26, while from the supplementaryl cowl 23 projectsV a supplementary wind shield 27 spaced from the primary one,

as plainly shown in Fig. 1, all of said parts coactingito form an air conduit 28, with an outlet 29; aboveor at the outer portion of the main wind shield, which outlet is controlled by a closure 30Vheld in diierent adjusted positions by a fastening means 31, such asa set screw carried by the closure and coacting with the slotted bracket 32, and in a similar manner the conduit 28 also leads to `another outlet 33 located above or in the outer portion of the supplementary wind shield, and may be directly opposite the outlet 29, and like the latter, the outlet 33 is controlled by a closure 34 hinged or otherwise mounted on a portion of the vehicle, and carrying fastening means 35 coacting with the slotted bracket 36. The brackets 32 and 36 may be mounted at the sides of the wind shields, or as shown, one may be secured to the visor and the other to the vehicle roof.

The lower part of the air conduit is closed by a transverse partition 37, and the space between the dashes may be divided by another partition 38 so as to separate one part from the other, and make one of these parts airtight; while the dashes may have holes therethru in the other part for the paa e of akchoke valve rod, ignition cables an the li e.

lVithi'n the vspace between the two dashes is mounted a blower 39, and itis to be understood that wherever the term blower is used, it is to include fans or other air n tatng instrumentalities in contradstiction to pumps er compressed air apparatus, and

lll

u able,'either opening` may be closed by the use of an imperforate plate 46, also having .key lhole slots 47 for coaction with the rivets 45. The shaftof the blower has gear 48 thereon to mesh with the gear 49 on the vertical shaft 50, the latter carrying one member of a clutch 51, while the other member thereof is mounted on astub shaft 52 upon which is mounteda gear 53 meshing with a gear 54 on the cam shaft, or other Yequivalent movable part .of the motor. The clutch may be Ycontrolled by a bell crank lever 56 which,rinv

turn is o erated bv a suitable actuat-inei mecha J if;

lanism 457, so arranged asto be accessible to the vehicle operaton Fromthe foregoing description it will be apparent that when the motor is' running and the clutch 'is thrown in, the blower 89 will re- "volve and cause 4air to blow through the'air conduit 28, being drawn into said conduit either throu'glrthe opening 40 from beneath vthe hood of the vehicle, to which I refer as the outside of thevehiele, or it may be drawn yfrom thefinside of the vehicle throughthe opening 41,l depending upon which opening "is closed by the iinperforate plate 46, although both vof the openings might be left uncovered, :and vair -drawn from both plaeesat once. The air passing through the conduit with .considerable force will be expelled through the outlet` 29 and then bailied or -guided by the closureBO so as toV direct the stream of air down across .the outside of the main wind shield 26, and 4any rain or snow coming Vwithin the region ofthis outside stream ofv -air will be carried along withl it and prevented from reachingthe wind shield, and therefore the latter is always Vkept clear so tliat'the vision'of the operator will be unobscured.

In order to overcome any likelihood'of the outside Streamof air being deflected by side Ywinds` dellecting wings 58 may be placed at both sides of that portion of the wind shield over which .the outside stream of air passes.

Where the wind shield is provided with the secondary opening 33, the device may be used for ventilating or cooling the vehicle as the closure 34 might be opened and the outlet 29 closed, permitting a stream of air to circulate within the body of the vehicle.

In Figs. 10, 11 and 12, I have shown the invention applied to another form of vehicle herein illustrated as a street or railway car 59, provided with lookout or vestibule windows 60 and above any or all of these windows is arranged the outlet end of an air conduit 61 leading from a blower The blower is supported on the vehicle in any suitable manner, and to the shaft 68 of the fan 64 is at ached an electric' motor 65, and it is to be understood that the casing of the blower is provided with theordinary air inlet 66, and may have an openingt7 controlled by a closure 68.V

At the outlet end of the conduit-61 is located a closure 69, which also acts as a deilector or baffle for deflecting the current of air issuing from the conduit across the lookout or vestibule window Aor windows, said closure being hinged orothe'rwise mounted for -inovement, and may be held in different adjustedV positions anisin 70. y

If found desirable, :detlecting wind shields 71 may be provided oneon each side of the path of travel of the-.air stream 'issuing from the conduit, f

In stormy weather, the device may be placed in operation, so that a stream of air will he projected in front of the lookout or vestibule window orwindows to prevent rain air which is used may be drawn from the i11- `terior ofthe car, its temperature can be higher than the outsideair, and so prevent the lformation of ice'on the window. During such times as the device is not being .used for keeping the windowsclear. the closure 68 may be opened, andthe conduit (i1-closed by the closure 69, thus causing a circulation of air within the vehicle. Y Y

InFigs. 5 and 6, I-have-illustrated another form of blower, in which a easing 72 is rovided, andthis is open at both ends with the shaft 73 of a motor 7 4 projecting into the same with ordinary fan blades 75 mounted thereon within the casing.

In Fig. '8 a blower is illustrated in which the casing 76 ris Vsimilar to the one shown in Fig. 12, but has only an air inlet 77, with the blower fan 7 8 located within the casing; in other words, the secondary outlet is `elimiiiated.

InvFig. 9, a casing 79 is shown having a vplurality of outlets 80 so that air moved by Vthe blower fan 81 within the casing may be distributed to a number of different points.

Of course I do not wishto be limited to the exact' details of construction as herein shown as these may be. varied within the limits of the appended claims without departing from the spirit of my. invent-ion.

Having thus fully described my invention, what I claim as new and useful is:

1. The combination with a vehicle proby `the operating mechvided with a window, of a blower, a conduit.v

leading from said blower toga point above the window; a closure for the outer end of said conduit adapted when open to deflect the stream `of air issuing from the conduit downward across the window; and wings on both sides of the path of travel of said air stream to prevent deflection of the latter by side winds.

2. The construction setforth in claim l, wherein the blower is provided with a secondary outlet controlled by a closure whereby an air stream maybe projected into the vehicle.

3. In combination, a vehicle having a pair of walls adjacent each other to form a portion of an air conduit; a pair of windows spaced apart to form a continuation of said air conduit; an outlet above each window; means to control said outlets; a blower located within the conduit and communicating with the interior and exterior of the vehicle; means to close either of said Vcommunications fortselectively drawing air into the conduit; and means controlling each outlet opening to selectively control the distribution of air passing through the conduit.

4. The structure set forth in claim 3; wherein a passageway is provided from the air conduit to the lower portion of the vehicle; and means to control the passage ot air through said passageway.

5. In a device of the character stated, the

combination of a motor-driven vehicle inand spaced from said main window,Vv all of Y said parts coacting to produce an air conduit having outlets above the windows; a blower provided with a shaft journalled within the conduit in the region of the inlets; means for transmitting motion from a suitable part of the vehicle motor to said blower; means to control the motion transmission means; closures for the outlets, one of which is adjust*- able to delect a stream of air issuing from the conduit across the outside of the main window; a closure for the passageway through the secondary cowl for controlling the passage of air from the conduit into the lower portioiroil the vehicle body; and means for closing either of the inlets to the conduit to selectively draw air into the conduit from the interior or exterior of the vehicle.

In testimony whereof, I have hereunto af- -fiXed my signature.
